Governor of Puerto Rico in the context of "Jenniffer González-Colón"

The government of Puerto Rico encompasses the local administrative structure of the archipelago and island of Puerto Rico, an unincorporated territory of the U.S. organized under the Constitution of Puerto Rico since its establishment as the Commonwealth of Puerto Rico in 1952. The government is a republican democracy divided into three branches: the law-implementing executive, the law-making legislative, and the law-interpreting judicial. The Governor is the chief executive, the Legislative Assembly is the legislature, and the Supreme Court is the highest court of the territory, which is divided into 78 municipalities, each one headed by a strong mayor and a unicameral legislature. Like U.S. states and other U.S. territories, Puerto Rico is subject to the sovereign jurisdiction of the U.S. federal government.

With the American annexation of Puerto Rico during the Spanish–American War, the U.S. established a military government to administer the unincorporated territory from 1898 to 1900, when it was replaced by a civil insular government organized under the organic acts of the Foraker Act from 1900 to 1917 and the Jones–Shafroth Act from 1917 to 1952. The Constitution of Puerto Rico established the Commonwealth of Puerto Rico and its government under the continued status of unincorporated territory in 1952. With the ratification of the constitution, the full authority and responsibility for the local administration of Puerto Rico was vested in the residents of Puerto Rico, resulting in complete self-governance within the archipelago and island.

Juan Ponce de León (c. 1474 – July 1521) was a Spanish explorer and conquistador known for leading the first official European expedition to Puerto Rico in 1508 and Florida in 1513. He was born in Santervás de Campos, Valladolid, Spain, in 1474. Though little is known about his family, he was of noble birth and served in the Spanish military from a young age. He first came to the Americas as a "gentleman volunteer" with Christopher Columbus's second expedition in 1493.

By the early 1500s, Ponce de León was a top military official in the colonial government of Hispaniola, where he helped crush a rebellion of the native Taíno people. He was authorized to explore the neighboring island of Puerto Rico in 1508 and to take office as the first Governor of Puerto Rico by appointment of the Spanish crown in 1509. While Ponce de León grew quite wealthy from his plantations and mines, he faced an ongoing legal conflict with Diego Colón, the late Christopher Columbus's son, over the right to govern Puerto Rico. After a long court battle, Colón replaced Ponce de León as governor in 1511. Ponce de León decided to follow the advice of the sympathetic King Ferdinand and explore more of the Caribbean Sea.

The Legislative Assembly of Puerto Rico (Spanish: Asamblea Legislativa de Puerto Rico) is the territorial legislature of the Commonwealth of Puerto Rico, responsible for the legislative branch of the government of Puerto Rico. The Assembly is a bicameral legislature consisting of an upper house, the Senate (Spanish: Senado) normally composed of 27 senators, and the lower house, the House of Representatives (Spanish: Cámara de Representantes) normally consisting of 51 representatives. Eleven members of each house are elected at-large rather than from a specific legislative district with all members being elected for a four-year term without term limits.

The structure and responsibilities of the Legislative Assembly are defined in Article III of the Constitution of Puerto Rico which vests all legislative power in the Legislative Assembly. Every bill must be passed by both houses and signed by the Governor of Puerto Rico to become law. Each house has its unique powers. The constitution also states that each house shall be the unique judge on the legal capacity of its members. The constitution also grants parliamentary immunity to all elected members of the Legislative Assembly.

The Constitution of the Commonwealth of Puerto Rico (Spanish: Constitución del Estado Libre Asociado de Puerto Rico, lit. 'Constitution of the Free Associated State of Puerto Rico') is the primary organizing law for the unincorporated U.S. territory of Puerto Rico, describing the duties, powers, structures, and functions of the local government of Puerto Rico and its relation with the U.S. in nine articles. Established under the Puerto Rico Federal Relations Act of 1950, it was approved by the residents of the archipelago and island in a constitutional referendum on March 3, 1952, ratified by the U.S. Congress as per Pub. L. 82–447 on July 3, 1952, and proclaimed into effect by Governor Luis Muñoz Marín on July 25, 1952, which is celebrated as Constitution Day. As the constitution of a U.S. territory, it is bound by the U.S. Constitution.

The Constitution of Puerto Rico established the Commonwealth of Puerto Rico, which succeeded the insular government that operated under two organic acts: the Foraker Act from 1900 to 1917 and the Jones–Shafroth Act from 1917 to 1952. With the ratification of the constitution in 1952, the full authority and responsibility for the local government of Puerto Rico was vested in the residents of Puerto Rico, resulting in complete self-governance within the archipelago and island.

La Fortaleza (English: "the fortress"), officially the Palacio de Santa Catalina ("Saint Catherine's Palace"), is the official residence and workplace of the governor of Puerto Rico. Located in the historic quarter of Old San Juan in the capital municipality of San Juan, it has served as the governor’s residence since the 16th century, making it the oldest executive mansion in continuous use in the New World. Built as a medieval fortress from 1533 to 1540 by orders of King Charles I of Spain, and remodeled to its present Neoclassical style in 1846 by orders of Governor Rafael Arístegui y Vélez, it was the first fortification erected by the Spanish on San Juan Islet to defend San Juan Bay, the harbor of Old San Juan. Alongside El Morro, San Cristóbal, and other forts part of the Walls of Old San Juan, it protected strategically and militarily important Puerto Rico, or La Llave de las Indias (The Key to the Indies), from invasion by competing world powers and harassment by privateers and pirates during the Age of Discovery and Sail. It was designated a World Heritage Site in 1983.

Situated in the western end of San Juan Islet in the Old San Juan historic quarter, La Fortaleza, seat of the executive branch, is about 1 mile (1.6 km) from the Capitol of Puerto Rico, seat of the legislative branch, in the center of the Islet in the Puerta de Tierra historic district, and 2 miles (3.2 km) from the Supreme Court Building, seat of the judicial branch, in the eastern end of the Islet in Puerta de Tierra.

The executive branch of the government of Puerto Rico is responsible for executing the laws of Puerto Rico, as well as causing them to be executed. Article IV of the Constitution of Puerto Rico vests the executive power on the Governor—who by its nature forms the executive branch.

The Constitution also establishes that the Secretary of State should serve as acting governor when the Governor is unable to perform his duties. The Secretary of State, therefore, performs an equivalent role to that of a Lieutenant Governor in United States politics.

The Foraker Act (Pub. L. 56–191, 31 Stat. 77, enacted April 12, 1900), officially called the Organic Act of 1900 and most commonly known by the name of its sponsor, Senator Joseph B. Foraker, (R-Ohio), is an organic act of the 56th United States Congress that was signed into law by President William McKinley on April 12, 1900. The Act replaced the military government of Puerto Rico, which was established by the United States after the annexation of the archipelago and island during the Spanish–American War in 1898, with a civil insular government under the continued federal jurisdiction of the United States as the local administration of an unincorporated territory. It served as the primary organic law for the government of Puerto Rico and its relation with the United States until it was superseded by the Jones–Shafroth Act of 1917.

The Foraker Act established a civil government in Puerto Rico modeled after the federal government of the United States. It divided the local government of the unincorporated territory into three branches: an executive, consisting of a Governor and an 11-member Executive Council appointed by the President of the United States, a legislative, composed of bicameral Legislative Assembly, with the Executive Council as its upper chamber and a 35-member House of Delegates elected by the residents of Puerto Rico as its lower chamber, and a judicial, headed by a chief justice and a district judge appointed by the President. The Act created the office of Resident Commissioner, a non-voting member to the United States House of Representatives elected by the residents of Puerto Rico. It also established Puerto Rican citizenship and extended American nationality to Puerto Ricans.

This list of governors of Puerto Rico includes all persons who have held the office of Governor of Puerto Rico since its establishment under the rule of the Spanish Empire (1508–1898) to the present under the sovereignty of the United States (1898–present).

The archipelago and island of Puerto Rico was annexed by the United States during the Spanish-American War in 1898, ending 390 years of active rule by the Spanish Empire, which began the European exploration, colonization, and settlement of the main island under conquistador Juan Ponce de León in 1508. Ponce de León was the first person to hold the title and office of governor by orders of King Ferdinand II of Aragon in 1509. The governor remained an appointee of the Spanish Crown during Spanish rule, and was an appointee of the President of the United States during American rule until 1948, when the residents of Puerto Rico began to popularly elect the governor, starting with Luis Muñoz Marín, who took office in 1949.
